This critical edition of Albert of Saxony's 25 Questions on Logic is a set of Quaestiones Disputatae which treats issues of the Parva Logicalia such as: the nature of logic; the imposition, distribution, signification, and supposition of designating and non-designating terms; the truth and falsity, conversion, contradictoriness, and kinds of propositions; and problems involving the scope of negations.
The inclusion of several appendices of previously untranscribed and unedited material by Albert of Saxony, Ralph Strode, and John Buridan; together with Notes and an Index of concepts and an Albert Concordance keyed to paragraph numbers, make the book a most useful source of primary material for students and scholars.
